WIRE-STRAIGHTENER.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed June 13. 1907. Serial No. 378.727.

To all whom it may concern:

Be it known that I, NOAH S. HARTER, of Waukegan, Lake county, Illinois, have invented a new and useful Wire-Straightening Mechanism, of which the following is a full, clear, and exact description, reference being had to the accom anying drawings, forming part of this speci' ication, in which Figure 1 is a longitudinal section of wire straightening mechanism embodying my invention; Fig. 2 is a plan view of the die-adjusting slide; and Fig. 3 is a section on the line IIIVIII of Fig. 1.

The object of my invention is to provide means for preventing injury to the wire at such times as it is necessary to stop the movement of the wire through the straightening mechanism for cutting or other operations thereon.

Heretofore it has been the practice to use a rotating straightening mechanism having a series of adjustable dies or blocks upon either side of the wire, one of which is usually adjusted so as to give the wire a considerable tension at this point, this die or block being the one that efiects the straightening as the series of dies are rotated around the wire while it is being drawn lengthwise through the straightener. With this mechanism, the adjustment of the straightening die or dies cannot be efiected while the machine is in motion, and the wire is continued to be gripped by the rotating die during the time that its forward motion is checked. This injures the wire at this point, both by the direct contact of the revolving die therewith, and also by reason of the fact that an apparent crystallization of the metal a pears to be efiected by the rotation of the die while the wire is stopped.

My present invention provides means wherebythe action of the straightening die on the wire can be relieved when the wire is stopped without stopping the straightener.

Referring to the accompanying drawing, the numeral 2 designates a hollow cylindrical body, which is mounted to rotate in suitable bearings 3 and which is driven by any suitable means such as the belt 4 and pulley 5.

6, 7, 8 and 9 designate a series of dies or blocks,which are adjustably secured in the body 2 by means of the screws 10, and which are so adjusted as to bear upon the wireA passing through the straightener body with out deflecting the same materially from a straight line.

11 designates the straightening die, which is seated in a movable yoke 12, and which can be adjusted by a screw 13 having a hearing in said yoke. 14 designates a slide, which is seated for endwise movement in the receiving end of the straightener body 2, with which body the slide rotates and through which the wire A passes. This slide carries the forwardly projecting arms 15, whose end portions are beveled on their under sides, as indicated at 16, said beveled portions extending over bearings 12' of the yoke 12. By reason of the bevel on the under side of the arms 15, as the slide 14 is moved forwardly, the yoke 12 will be moved at right angles to the path of movement of the wire A, to cause the die to be tightened to give a greater deflection oi the wire between the dies 7 and 8; while when the slide 14 is moved backward, the tension of the die 11 is decreased.

The rear end portion of the slide 14 projects beyond the rear bearing 3, and is engaged by a shifting or actuating lever 17. This lever may be operated either manually, or automatically by connection with a mov ing art of some machine, such as a coiling mac line, to which the wire A is led after leaving the straightener, the pur ose being to provide means whereby the saic slide may be actuated to cause the die 11 to grip or release the wire A at any time without stopping the rotation of the straightener. By this means all injury to the wire due to the continued rotation of the straightener is avoided.

It will be understood that this invention is applicable wherever it is desired to straighten wire and, without regard to the source from which the wire comes or to where it proceeds, provided the subsequent operations upon the wire are such as to necessitate more or less frequent stoppage of its forward movement.

Various changes may be made in the details of construction and arrangement of parts without departing from my invention, smce What I claim is 1. A Wire straightener having a plurality of rotary dies, and means for adjusting one of said dies Without stopping its rotation; substantially as described.

2. A die straightener having a rotary body, through which the Wire passes, a plurality of dies arranged to bear upon the Wire, and means for adjusting one of said dies Without stopping the rotation of the body; substantially as described.

3. A Wire straightener having a rotating body, a straightening die therein, and means for adjusting said die While the body is rotated; substantially as described.

4. A Wire straightening device having a rotating body, a straightening die therein, a movable carrier for said die, and an adjusting device engaging said carrier and arranged to be operated Without stopping the rotation of the body; substantially as described.

5. A Wire straightener having a rotating ating said slide from the exterior of the body;

substantially as described.

*7. A Wire straightener having a rotating body, an adjustable straightening die there in, a slide rotatable with said body and movable longitudinally therein, and means for actuating said slide from the exterior of the V I body; substantially as described.

In testimony whereof I have hereunto set my hand.
